Summary
CETIN Hungary
mobile eyeball wholesale legacy
CETIN Hungary Zrt. (CETIN-HU) — the wholesale network-infrastructure company spun out of Telenor Hungary in 2020, headquartered in Törökbálint. It owns and operates the mobile access network that Yettel Hungary, its principal customer, runs its retail service on.
What it's used for
- Subscriber access. The largest announced block resolves as
IP-ADDR-IP-ADDR.dynamic.cetin.hu— dynamic end-user pools, i.e. Yettel's customers numbered out of the infrastructure company's address space. - A smaller legacy block carries corporate hosts on customer-owned domains.
Notable
- A kind trap worth being explicit about: the holder is a wholesale infrastructure operator with no retail customers of its own, but the addresses are ordinary consumer devices. Classify by what the space carries, not by the company's business model.
- Users geolocate across Hungary generally; Törökbálint is only the registered office.
Interesting
- The infra-company split (network assets in one entity, brand and customers in another) is a recurring pattern in the PPF/e& telecom group, and it routinely leaves the eyeball traffic announced from an AS whose name no subscriber has ever heard of.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
